What is the number?
A.=-5
B.=1
C.=5
D.=11

Step-by-step explanation:

The number n is - 5

Because the sum = 8 + (-5) = 3

After multiply by - 4 = 3 x - 4 = - 12

Option A is the correct answer

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
